Description

用于个人信息检索、更新和表示的方法和系统 Methods for personal information retrieval, update, and represented and systems

技术领域 FIELD

本发明涉及一种信息检索与组织系统和方法,尤其涉及一种用于(以创建个性化信息源的形式)检索、处理和表示来自多种信息源,如无线电、电视或互联网,的内容的系统和方法。 The present invention relates to an information organization and retrieval system and method, particularly to a (in the form of creating personalized information source) retrieval, processing and presentation of information from a variety of sources, such as radio, television or the Internet, content systems and methods.

背景技术 Background technique

现在有大量可利用的电视频道、无线电信号和通过互联网可以访问的几乎无限的内容流。 There are a large number of available TV channels, radio signals and virtually unlimited content can be accessed via the Internet stream. 但是,这大量的内容使得很难找出特定观众要寻找的内容类型,而且还很难个性化在一天中不同时间可访问的信息。 However, this large amount of content makes it difficult to find a specific type of content viewers are looking for, but also difficult to personalized information at different times of day can access.

通常,广播电台尤其难以根据内容进行搜索。 Typically, the radio station is particularly difficult to search by content. 电视服务提供了收视指南,并且在特定情况下观众可以换到导视频道并观看正在播放或将在不同时间段内播放的级联的节目信息流。 TV Program Guide service is provided, and the audience can change under certain circumstances to Guide channel and watch the program information flow cascade being played or will play in different time periods. 所列出的节目按频道的顺序滚动,观众对这种滚动不能控制,而且通常不得不一直坐到很多频道都显示完以后才能去找自己想看的节目。 Programs listed in the order of channel scroll, scroll audience that can not be controlled, and usually have to sit through in order to find the program you want to see after many channels have been displayed. 在其它系统中,观众在他们的电视屏幕上访问收视指南。 In other systems, the viewer access to the Program Guide on their TV screen. 这些服务通常不允许用户搜索所显示电视节目中的特定内容,如电视剧的一个片段。 These services are usually not allowed TV show specific content, such as a segment of TV users to search the display. 例如,观众可能只对本地新闻广播中的体育部分感兴趣。 For example, a viewer may only be interested in the sports section of the local news broadcast.

在互联网上,寻找内容的用户可以在搜索引擎中输入搜索请求。 On the Internet, looking for content users can enter a search request in the search engines. 但是,搜索引擎有可能不能有效地被利用而且常常将用户指引到不希望的网站。 However, the search engines may not be effectively utilized and often direct users to unwanted websites. 此外,在获得想要的信息之前这些网站要求用户登录,而且浪费时间。 Also, before you get the desired information these sites require users to log in, but also a waste of time.

其内容在此引入作为参考的美国专利No.5,861,881描述了一种能够在计算机网络上运行的交互式计算机系统。 Which is incorporated herein by reference U.S. Patent No.5,861,881 describes an interactive computer system capable of running on a computer network. 用户通过使用输入设备和个人计算机或电视与交互式节目进行交互。 User interaction by using an input device and a personal computer or TV with interactive programming. 多种视频/音频数据流可以从广播发射源接收或者驻留在本地或外部存储器中。 Multiple video / audio data streams can be transmitted or received from a broadcast source resides in the local or external memory. 因而,'881专利仅仅描述了从一组预定义的可选方案中选择一种可选数据流,而并未提供搜索观众感兴趣的信息以创建用于接收信息的个性化信息源的方法。 Thus, the '881 patent describes only select an alternative data stream from a set of predefined alternative, but does not provide information of interest to the viewer to create a method of searching for receiving personalization information of the source information.

其内容在此引入作为参考、标题为“Interactive Play ListGeneration Using Annotations”的WO 00/16221描述了用户选定的多个注解如何用于定义对应于这些注解的媒体片段的播放列表。 Contents of which are incorporated herein by reference, entitled "Interactive Play ListGeneration Using Annotations" WO 00/16221 describes a plurality of annotations for defining how the user-selected media segment corresponding to the annotated playlist. 然后,用户选定的注解及它们对应的媒体片段可以无缝方式提供给用户。 Then, user-selected annotations and their corresponding media segment may be provided to the user in a seamless fashion. 用户界面允许用户改变播放列表及播放列表中的注解顺序。 The user interface allows users to change the order of play lists and notes in the playlist. 因此,该用户界面利用很短的主题行识别每个注解。 Thus, the user interface is extremely short subject line to identify each comment.

因此,′221文献描述了一种在流式视频服务器中通过网络计算机系统产生视频播放列表的完全手动方式。 Thus, the '221 document describes a completely manual way of generating a video playlist in the computer system through the network streaming video server. 用户界面在具有双屏幕的客户计算机上提供了一个视窗。 The user interface provides a window on the client computer with a dual screen. 用户根据注解中的信息选择要检索的视频。 Select the annotation user information in accordance to retrieve the video. 但是,选择仍然需要由用户进行,并且依赖于界面的精确性和完全性。 However, it still needs to be selected by the user, and relies on the accuracy and completeness of the interface.

其内容在此引入作为参考、标题为“Contents Extraction Methodand System”的EP 1 052 578 A2描述了一种之前利用表示用户喜好的用户特征化数据进行记录的用户特征化数据记录介质。 Contents of which are incorporated herein by reference, entitled "Contents Extraction Methodand System" in EP 1 052 578 A2 describes the user prior to use one kind of characteristic data indicating the user preferences for recording user characteristic data recording medium. 它装载在用户终端设备上,从而用户特征化数据可以记录在用户特征化数据记录介质上并输入到用户终端单元。 It is loaded on the user terminal device, so that the user characteristic data may be recorded on the user characteristic data recording medium and input to the user terminal unit. 以这种方式,当检索键盘识别出用户感兴趣的多媒体内容特征时,多媒体内容可以利用输入的用户特征自动进行检索。 In this manner, when the multimedia content retrieved keyboard identified features of interest of a user, the multimedia content can be automatically retrieved using the inputted user characteristic. 根据检索结果,期望的内容就可以选定、提取并显示。 According to the search results, select the desired content can be extracted and displayed.

因此,′578文献的系统搜索广播系统中的内容或搜索符合观众兴趣的多媒体数据库。 Therefore, the '578 system searches for broadcasting system in content or literature search in line with audience interest in multimedia database. 它没有关于根据本发明可以实现的分割视频及检索片段的描述。 It does not describe about the segmentation may be implemented and the search video clips according to the present invention. 这种系统还要求使用存储在数据库中或发送到广播系统的附属于多媒体内容的关键字。 The system also requires the use of a keyword storage system affiliated broadcast multimedia content in a database or sent to. 因此,它不提供不需要使用发送或存储的关于多媒体内容的关键字的系统。 Therefore, it does not provide key system on multimedia content does not need to send or store. 它不提供可以利用现有数据,如字幕,或声音识别来自动提取匹配的系统。 It does not provide a utilization of the data, such as subtitles, or a voice recognition system to automatically extract the match. ′578参考内容也没有描述提取广播中相关部分,如仅仅是早间新闻中的本地交通部分,的系统。 '578 references do not describe the extraction broadcast in the relevant part, as just part of the morning news in local traffic, the system.

因此,不存在完全方便的系统和方法允许用户只搜索满足其个人兴趣的媒体内容。 Therefore, complete and convenient system and method does not exist to allow users to search only meet their personal interests of media content.

发明内容 SUMMARY

总的来说,根据本发明,提供了一种信息检索系统和方法。 In general, according to the present invention, there is provided an information retrieval system and method. 为了确定内容是否满足预定义的用户简档,对来自各种信息源,如电视、无线电和/或互联网,的内容进行分析,其中用户简档对应于手动或自动创建的用户信息源。 In order to determine whether the content meets a predefined user profile, content from various information sources, such as television, radio, and / or the Internet, is analyzed, wherein the user profile information corresponding to the user manually or automatically created source. 然后,个性化的信息源被自动创建以允许访问音频、视频和/或文本形式的信息。 Then, the information source is personalized automatically created to allow access to audio, video and / or text message. 以这种方式,可搜索媒体内容的范围就能够缩小到只有那些用户感兴趣的节目或者节目的部分或片段。 In this manner, the search for media content range can be reduced to only those programs or program portions or fragments of interest to the user. 信息检索可以通过PDA、无线电、计算机、MP3播放器、电视等来实现。 Information retrieval can be achieved by PDA, radios, computers, MP3 players, televisions and so on. 因此媒体内容的范围就缩小到个性化组。 The scope of media content will be reduced to a personalized set. 例如,用户可以不仅仅接收天气或交通,还可以接收最相关的天气或交通。 For example, users can not receive weather or traffic, weather or traffic may also receive the most relevant. 此外,该系统还能够根据用户的兴趣改变分析,例如,早上显示当前的交通状况,而晚上则显示第二天的交通警报。 In addition, the system is also able to change according to the user's interest analysis, for example, displays the current traffic conditions in the morning, and evening traffic alert the next day is displayed. 该系统还能够自动检测特定时间的用户兴趣并依照惯例,如天气优先,来传递信息。 The system can also automatically detect user interest and in accordance with the practice of a particular time, such as weather priority to transmit information.

因此,本发明的一个目的是提供一种改进的基于自动个性化组织、检索并观看媒体内容的系统和方法。 It is therefore an object of the present invention to provide an improved system and method for automatically personalized based organizing, retrieving and viewing media content.

具体实施方式 detailed description

本发明针对一种根据预先选定或自动的用户简档从多种媒体信息源中检索信息,以便提供根据个性化信息源提供可即时访问信息的系统和方法,其中个性化信息源可以利用最新的数据自动更新,从而用户能够即时访问最新的可用数据(节目安排)。 The present invention is directed to a preselected or automatically retrieve user profile information from a variety of media sources of information, in order to provide a system and method for providing instant access to the information according to the personalized information source, wherein the source of personalized information may be utilized Latest the data is automatically updated so that users can have instant access to the latest available data (programming). 这种数据可以从多种信息源,包括无线电、电视和互联网,收集。 Such data may be from a variety of sources, including radio, television and the Internet, collect. 在数据收集到以后,它可以作为视频、音频和/或文字用于观看、收听、阅读或,例如,当作节目的一部分下载到计算机或其它存储媒体中,用户还可以从那组数据中进一步下载信息。 After the data is collected, it can be used as video, audio and / or text for viewing, listening, or reading, for example, as part of a program downloaded to a computer or other storage media, users can also further from that set of data download information.

用户可以提供手动或自动产生的简档。 Users may be provided manually or automatically generated profile. 例如,用户可以选择简档中的每个要素或者例如通过点击屏幕或按下按钮从一组预先选定的简档,如体育、新闻、电影、天气等,中进行选择。 For example, the user can select each element in the profile or selected, for example by tapping the screen or press the button from a group of pre-selected profile, such as sports, news, movies, weather, etc., in. 这也可以自动完成。 This can also be done automatically. 可以对选定的节目进行分析,而分析的要素可以用于编辑简档。 It can be analyzed for selected programs, and factor analysis can be used to edit profiles. 然后,计算机可以搜索电视、无线电和/或互联网信号来找出与该简档匹配的条目。 Then, the computer can search for television, radio and / or the Internet to find signals that match the profile entry. 在这一步完成以后,就可以创建用于访问音频、视频或文本形式信息的个性化信息源。 After this step is completed, you can create personalized information source access audio, video, or text message. 如果最近的信息比较新并且至少同样完整(而不是比较不完整的子集),则这种信息源可以利用最近的信息进行定期更新。 If the most recent information is relatively new and is at least as complete (rather than the more incomplete subset), the source of this information can be regularly updated using the most recent information. 然后,信息检索可以由PDA、无线电、计算机、电视、VCR、TIVO、MP3播放器等来完成。 Then, information retrieval can be done by PDA, radio, computer, TV, VCR, TIVO, MP3 players.

因此,在本发明的一种实施方案中,用户利用交互式电视系统在计算机或屏幕上输入或点击各种简档兴趣选项。 Thus, in one embodiment of the invention, the user using the interactive television system or clicking on the various input options profile interest or on a computer screen. 语音接口、手势和其它交互方法都可以采用。 Voice interface, gestures and other interactive methods can be used. 然后,对选定的内容进行搜索、定位并下载,以便以后观看和/或为了立即观看使用户可以访问它们,从而在作出收视选择之前只需要访问小得多的选项范围。 Then, the selected content to search, locate and download for viewing later and / or for immediate viewing allows users to access them, thus making before viewing options only need access to a much smaller range of options. 例如,如果观众只想看电影,则输入MOVIE可以用于将他的收视选择缩小到那些播放电影的电视台。 For example, if viewers want to watch a movie, MOVIE can be used to enter his television viewing options narrowed down to those playing movies. 可选地,用户可以访问在那一天、那一周或其它预定时间段播放的所有电影。 Alternatively, a user can access on that day, the week, or other predetermined period of time to play all the movies.

一种特定的不受限实例是为用户定义其简档包括来自各种信息源的天气、交通、股市、体育和头条新闻。 A specific example is not limited to a user-defined profiles that include weather information from various sources, traffic, stocks, and sports headlines. 用户还可以在简档中包括地理和时间信息。 Users can also include geographic and time information in the profile. 最好的交通信息源可能是能够每十分钟就提供更新的本地广播电台。 The best traffic information sources may be able to provide updates every ten minutes on a local radio station. 股市信息从各种财经或新闻网站可能能够最好地访问到,而天气信息可以从专门用于天气报告的互联网网站、本地早间新闻广播或本地早间无线电广播检索到。 Financial or stock market information from a variety of news sites may be able to better access to, and the weather information can be used for weather reports from a dedicated internet site, local morning news broadcast or the local morning radio broadcast retrieved. 对这些信息进行编辑并使用户可以访问它们,用户将不需要切换可能好几百个频道、广播电台和互联网网站就可以自动地使与其预先选定简档匹配的信息直接变得可用。 These information editing and enable users to access them, you probably will not need to switch hundreds of channels, radio stations and Internet sites can automatically make its advance information of the selected profile matches directly become available. 此外,如果用户想开车去上班但已经错过了本地交通报告的广播,那么他可以访问并重播该交通报告。 In addition, if the user wants to drive to work but have missed the broadcast of local traffic reports, and then he can access a replay of the traffic reports. 此外,他还可以获得该信息的文字简述或阅读该文字的合成播音员,或者将该信息下载到音频系统,如MP3存储设备,用于以后收听。 In addition, he can get the information or the text briefly synthetic announcer reading of the character, or download the information to the audio system, such as MP3 storage device for later listening. 然后,他就可以在坐进汽车以后收听刚才错过的交通报告。 Then, he can listen to traffic reports just got into the car after a miss.

现在看图1,根据本发明一种不受限的优选实施方案,示出了一种用于接收信息、处理信息并使用户可利用该信息的系统100的方框图。 Turning now to Figure 1, according to a preferred embodiment of the present invention is not limited to one kind, it shows a block diagram of a receiving information, processing information and the user can use the information system 100. 如图1所示,系统100不断地从各种广播源接收输入。 As shown, the system 100 continually receives input from a variety of broadcast sources. 因此,系统100接收无线电信号101、电视信号102和通过互联网的网站信息信号103。 Thus, system 100 receives a radio signal 101, the television signal 102 and the Internet site information signal 103. 无线电信号101通过无线电调谐器111来访问。 The radio signal 101 via access 111 radio tuner. 电视信号102通过电视调谐器112来访问,网站信号103通过网络蜘蛛113来访问。 Television signal 102, signal 103 site accessed over a network 113. TV tuner 112 to the spider accessed.

接收到的信息类型将从所有领域接收,可以包括新闻广播、体育信息、天气报告、财经信息、电影、喜剧节目、交通报告等。 The type of information received from receiving all areas may include news broadcasts, sports information, weather reports, financial information, movies, comedy shows, traffic reports. 然后,多源信息信号120发送到用于分析信号以便提取出上述识别信息并将信号151发送到用户简档比较处理器160的即时信息处理器150。 Then, a signal transmitted to the multi-source information for analyzing the signal to extract the signal 151 and the identification information transmitted to the user profile information comparison processor 160 the instant the processor 150,120. 用户简档处理器160将识别标准与简档进行比较并输出表示特定内容源与简档是否匹配的信号161。 The user profile identification processor 160 compares the profile standard, and outputs a signal indicating whether a particular content source 161 and a profile matching. 简档160可以自动创建或从多个预先格式化好的简档中选择。 Profile 160 can be automatically created or pre-formatted profile selected from a plurality of profiles.

如果信息与简档不匹配,则按照用户兴趣赋予其低优先级,而系统100继续从下一个内容源提取附加信息的过程。 If the information does not match the profile, the user's interest according to impart a low priority, and the system 100 continues the process of extracting additional information from a content source. 联系本发明的某些实施方案,足够高的广播员重要性有可能使其成为高优先级条目。 Certain embodiments of the present invention to contact, announcer sufficiently high importance is likely to become a high priority entry. 因此,在本发明的某些实施方案中,当没有与简档的匹配时,内容不是丢弃而是按优先级排列。 Thus, in some embodiments of the present invention, when there is no match with the profile, rather than discarding the contents are prioritized. 当内容是冗余的或需要空间时内容才被“丢弃”,最低优先级的信息被丢弃。 When the content is redundant or need space content was only "dropped", the lowest priority information is discarded.

一种处理所接收到的信息并将其与简档进行比较的优选方法在图2的流程图中作为方法200更加清晰地示出。 An information processing of the received and preferred method as a method of comparison 200 more clearly shown in the flowchart of FIG. 2 with the profile. 在方法200中,输入信号120′是从各种内容源接收的。 In the method 200, the input signal 120 'received from various content sources. 在步骤150′中,可以包括缓冲器和计算机的即时信息系统150(图1)通过字幕信息、音频到文字识别软件等提取信息并自动执行关键字搜索。 In step 150 ', the buffer may include instant messaging system and the computer 150 (FIG. 1) by the subtitle information, audio-to-text recognition software to extract information and automatically perform a keyword search. 例如,如果即时信息系统150检测到单词“天气”,加上地点、可能还有与电视广播关联的字幕信息中一天中的某个时刻或网站的标签信息,那么它将使得该广播或网站可以作为个性化信息源的一部分用于选择。 For example, if the instant messaging system 150 detects the word "weather", with location, label information may also caption information associated with the television broadcast of the day at some point or the website, it will make the broadcast or Web site can as part of personalized information for selecting a source.

在步骤220中,将提取出的信息(来自步骤220的信号151)同用户简档进行比较。 In step 220, the extracted information (signal 151 from step 220) is compared with the user profile. 如果信息与用户兴趣221不匹配,则该信息被忽略,对下一个内容源继续提取信息的过程150′。 If the information does not match the user's interest 221, then the information is ignored, continue to extract information of the next content source process 150 '. 当找到一个匹配222时,在步骤230中对该信息进行检查以确定该信息是否比个性化信息源中现有的信息更新而且不是其子集。 When a match is found 222, in step 230 the information is checked to determine whether the source of the information than personalized information and updating existing information is not a subset thereof. 如果包含在信号中的信息显示它比较旧231,则它被忽略而提取过程150′继续。 If the information contained in the signal 231 to display it is relatively old, it is ignored and the extraction process 150 'continues. 如果较新信息检查步骤230显示该信息比较新232,则在步骤240中系统100用它取代个性化信息源中比较旧的信息或创建新的信息源。 If a newer information checking step 230 displays the new information comparison 232, then in step 240 the system 100 which replaces the personalized information in the older information source or create new information sources.
